Question

If SinA = 1/2 and cosA=1/2 then the value of A + B is​

Answer 1

Answer: (A + B) = 90°.

Explanation:

We know, sin 30° = ½ = cos 60°.

So, sin A = sin 30° and cos 60° = cos A.

∴ A + B = 30° + 60° = 90°.

Answer 2

Answer:

If SinA = 1/2 and cosA=1/2 then the value of A + B is 90°

Step-by-step explanation:

A + B = 30° + 60°

= 90°
